Background

Status:	Approved
Date Posted:	Apr 22, 2009
Sponsor:	ERCOT
Urgent:	No
Sections:	7.2.2
Description:	This Operating Guide Revision Request (OGRR) adds additional monitoring and control requirements for Special Protection Systems (SPSs) that involve generation reduction.
Reason:	ERCOT observed several SPS operations in 2008 that occurred under normal loading without any system disturbances. The revision presented herein places an obligation on Resource owners who have an SPS to monitor the flows monitored by the SPS in the base case and reduce output as needed before the arming point of the SPS is reached.
